. for the The lower portion of the tank 3 is adapted for the reception of the condensed water for use in the boiler by means of a water proof bottom 19 positioned therein. This bottom 19 is equip ed with a conventional drain 20 which may be utilized to drain oil the water when the system is not in use.

For the admission of make-up water to the tank 3 at the beginning of the operation, the aalve 21 is provided which valve may be of the whistle type or of any other conventional construction. This valve is positioned immediately above the pan 9 which pan as will later be shown is adapted to heat the makeup water. The pan is aperture'd at the center 'assage of steam tlierethrough in a manner Tater to be described.

The valve is actuated by a float 2 2 positioned in the tank 3 at the water level which float 22 is pivotally mounted in the wall of the tank 5 as shown at 23 and connected to the operating lever 24 by an adjustable connecting rod 25. The pivot mounting frame 26 may be removed from the wall of the tank 3 for disassembly, I p

To protect the float from mud and mudforming matter contained in the exhaust steam passing between the battle 8 and the wallll and thereabove an additional battle 27 is mounted on the wall 11 to project above said float. It can easily be seen that any foreign matter tending to fall down upon the float will strike this baflie 27 to be carried oil to one side of the float. I

For lowering the temperature of the steam for condensing the same a plurality of steam pipes 28 are positioned on the top of the tank and in communication with the interior tl'iere-' of. These steam pipes 28 are mounted between the top 29 of the tank 3 and the bottom 30 of the member 31 of my apparatus which I call a mist extractor. They are placed in spaced relation and exposed to the atmosphere to radiate heat from within. The mist extractor 31 is supported on the tank 3 by means of I-beams 32 which may be secured to the tank and the mist extractor by any suitable means. This mist extractor is construc ed in a manner similar to the mist extractor disclosed in my United States Patent No. 1,695,192, issued Dec. 11, 1928, and comprises the lower floor 30 through which the steam pipes 28 project, an upper partition wall 33 in which a series of chimneys 34 are positioned immediately above the respective steam pipes 28 and a top or cover 35 having a steam outlet 36 to the atmosphere or to other condensing mechanism. The floors 30 and 33 are further provided with drains 37 and 38 respectively, through which the water contained in the mistextractor flows downwardly through the steam pipe 39 in drain 38 and pipe l0 in drain 37. This pipe lO connects to the pipe 41 which comprises the feed water outlet for connection to the feed means leading to the boiler. The pipe l1 it will be observed is provided with apertures 42 which permit the water in the tank 3 therein to be carried to the boiler for use.

The steam pipes 28 are equipped for a distance of about six inches of their length at the top thereof on their interiors with strips of twisted metal l3 which strips of twisted metal impart to the upwardly flowing stream an outwardly whirling motion for an operation soon to appear.

The mist extractor is also provided with a blow-oil a l which blow-oili may be utilized for extracting drinking water, etc., there-' from. V

Suitable gages 45, 48 and 457 are positioned on the outside of the tank 3 for indicating the water and the oil levels respectively.

From the -foregoing description, the use and operation of this portion of my mecha nism is easily understood. The steam from the machinery or other means operated from the boiler passes through the inlet 6 to engage the baflle 8. The lubricant and other foreign matter because of its weight falls on the baffle 18 and passes into the compartment 10 for subsequent disposal through the blow-oft 16. The steam then passes between baflie 8 and wall 11 through the aperture in pan 9 into steam pipes 28. Any mud or mud-forming materials contained in said steam falling downwardly after passage over the wall 11 will be shunted, by the baliie 27 beyond the float 22 without disturbing the functions thereof.

The steam rising upwardly in the steam pipes 28 is engaged by the twisted strips of metal to pass from the tops of said steam pipes in an outwardly-moving whirl. At this point the steam encounters a dead space and thereafter deposits the droplets of water formed therein by whirling them clear of the tubes. The steam particles being lighter than the liquid particles are not whirled to such a distance so that the greater part of them pass through the chimneys 34 to be discharged through the outlet 36. Some of the steam in the space above the plate 33 will be condensed by contact with the air cooled outer wall and top wall 35 and the condensate will collect on the plate The deposits of liquid on plates 30 and 33 pass through the drains 37 and 38 and through. pipes 39 and 40 and pipe 41 to be conducted therefrom to the boiler for use.

During the passage of the steam about and through the aperture of the pan 9 the makeup water is heated before it flows through the aperture therein to fall into the lower portion of the tank 3. The float of course controls the admission of this make-up water as needed.

Attention is now directed to Figures 1, 6 and 7 wherein is disclosed the secondary unit of my invention. erates upon the same principle as the primary unit with the exception that it is not equipped with make-up water supply means or means for extracting lubricant and other foreign matter from the water.

It consists of a tank 48 having a drain 49, a feed water outlet 50 in which the feed water is conducted to the boiler and an exhaust inlet 51 similar to the exhaust inlet 6 of my primary structure. This exhaust inlet 51 is connected in my assembly to the outlet 36 of the mist extractor of the primary unit by means of a pipe 52. It is in this tank 48 that the feed water is collected after the condensation thereof for utilization in the boiler.

For cooling the steam admitted into tank 48 through inlet 51 for subsequent use in the boiler a system of steam pipes 52 are positioned above the tank 48 and in communication therewith. These pipes 52 are supported by the top 53 of the tank 48 and the bottom 54 of the mist extractor 55. They are placed in spaced relation and exposed to the atmosphere for purposes of radiating heat from the steam within.

The mist extractor 55 is supported as in the primary unit by means of beams 56 cooperating therewith and with the tank 48. These beams are secured about the tank 48 and mist extractor 55 by means of bands or girdles 57 which bands or girdles may be constructed of any convenient material, and

in any fashion. It is obvious that other fasteners could well be used.

The mist extractor 55 is of a construction similar to the mist extractor 31 and has similar fioor walls 58 and 59 with the ends of the pipes 52 projectin g through the wall 58 and.

chimneys 60 in the wall 59. Suitably spirally-twisted pieces of metal 61 are positioned in the pipes 52 as in the primary unit to give the ascending steam a whirling motion. The floors 58 and 59 are also equipped with drains 62 and 63'communicating with pipe 64 in the case of drain 63 and with pipe 65 in the case of drains 62 and 63 for draining the contained liquid from the floors back into thetank 48 for usein the boiler. In this unit no cover is provided for the mist extractor, the same being open at the top and exposed to the atmosphere for releaseof air and any uncondensed steam.

' comes in the inlet 51 passes upwardly through p the pipes 52 to be cooled and is then whirled from the upper ends of the pipes into the This secondary unit optankwhile the air passes 05 into the atmosphere. The water in the tank 48 may then be utilized for the boiler water.

The two units are interconnected by pipes 6'7v and'68having valves 69 and 7 0 respectively positioned in the lines for controlling flow of water from the respective units. These pipes 67- and 68 communicate witha pipe 71 which conducts the water to the boiler by way of pumps or other suitable apparatus utilized in the feed water system for introducing water into said'boiler.

The tank 3 is fitted with a man-hole 7 2 to allow entry therein for cleaning purposes. A

similar man-hole not shown maybe used in tank 48 to enable workmen to clean the same.

It will be observed that the unit 2 iscf greater height than unit 1, thereby assuring rising of the steam therein from unit 1 and diffusion of the air coming from the top thereof into. the atmosphere. A

It is thus seen that I have provided a means for recoveringthe steam utilized in the operation of machinery for subsequent use in the boiler that supplies the power for the operation of said machinery which frees said steam from lubricant and other foreign matter contained therein and recovers said steam for use as boiler'water by a simple and effective apparatus.
